Key Features: Over-collateralized loans, DAI stablecoin minting, decentralized governance
TVL: Controls ~30% of the stablecoin lending market
MakerDAO remains central to DeFi’s stability through its flagship DAI stablecoin, which is soft-pegged to the US dollar. Users lock up crypto assets like ETH or LSTs to generate DAI, enabling leverage or off-ramping without selling holdings.
Beyond crypto collateral, MakerDAO has expanded into real-world finance (RWF) with vaults backed by short-term treasuries and corporate loans. This diversification strengthens DAI’s peg while offering sustainable yields to backers.
Euler: Permissionless Innovation with Strong Security
Blockchains: Multi-chain EVM networks
Key Features: Permissionless token listing, vault isolation, risk-adjusted loan-to-value (LTV), DeFi-native rewards
Ranking: Top 10 lending protocol by innovation and security
Euler stands out for allowing any ERC-20 token to be listed as collateral without gatekeeping—a bold move that fosters inclusivity. To mitigate risk, it uses modular vaults that isolate exposure and apply dynamic LTV caps based on asset volatility.
Backed by over 40 audits from top firms like OpenZeppelin and Quantstamp, Euler combines cutting-edge design with rigorous security—a rare balance in fast-moving DeFi.
Morpho: Peer-to-Peer Yield Optimization
Blockchains: Ethereum, Base
Key Features: P2P matching layer, zero borrow fees, capital-efficient vaults
TVL: ~$6.3 billion
Morpho enhances existing lending pools (like Aave and Compound) by introducing a peer-to-peer overlay that matches lenders and borrowers directly. This reduces reliance on pooled liquidity and often delivers higher yields for savers and lower rates for borrowers.
Its vault-based structure improves capital efficiency while maintaining compatibility with underlying protocols. Multiple audits from Spearbit and OpenZeppelin reinforce its trustworthiness.

Spark Protocol: Stablecoin-Centric Lending
Blockchains: Ethereum, Gnosis
Key Features: SPK governance token, multi-collateral lending, stablecoin yield optimization
TVL: ~$4.4 billion
Originally spun out from MakerDAO as “Sky,” Spark focuses on stablecoin deposits and low-volatility lending. It integrates tightly with Maker’s ecosystem while offering community-driven upgrades and flexible borrowing options.
Spark’s emphasis on capital preservation makes it ideal for users seeking predictable returns without exposure to volatile crypto assets.
Kamino Finance: Solana’s Liquidity Leader
Blockchain: Solana
Key Features: Concentrated liquidity pools, leveraged “Multiply” positions, native asset support
TVL: ~$3.6 billion
On the high-speed Solana network, Kamino Finance leads in lending and borrowing innovation. Its “Multiply” feature allows users to leverage positions using concentrated liquidity strategies similar to Uniswap V3.
With deep integration into Solana’s DEX ecosystem, Kamino enables seamless borrowing against LP tokens and other native assets—making it a hub for active traders and yield farmers.
Suilend: Sui’s High-Yield Contender
Blockchain: Sui
